For those of you with iPhones / iPads - Canon Singapore released an App on 22 Dec 2011 detailing all the currently available Canon Lenses. It has nice features like Depth of Field calculations etc.Despite being from Canon Singapore, it appears to be available worldwide (I think?)

It doesn't have the calculators, etc., but does have links to several reviews for each lens.

Fanboi app? I'd feel like a work-for-free salesperson for Canon

Personally, I feel like someone who enjoys spending time helping others by answering their questions, ideally with detailed, factual information. But if you'd rather view that as a waste of time or fanboi-ism, suit yourself.

Never said it was a waste of time. It is more like a sales tool than anything else. Would be interesting if the non-corporate apps will get updated often.
